I might point out that there are two sets of these bilaterally, but in any
event that puts you back at a head centered coordinate system. The vestibular
system at its heart is a motion detector. I would look elsewhere for a neural
system that contained an animal centric "center" representation. Probably
something connecting the hippocampus and the anterodorsal thalamic nucleus, but
that's just wild speculation on my part.
